Did you bring up a mixer and make sure the volume is turned up, and not muted?

If yes, run the command '/sbin/lsmod | grep snd' ( without the quotes and post the results. As well as the sound driver, your should see several other lines. Here is an example.

Code:

Hi,
I see a similar problem. I'm running Fedora Core 6 with 2.6.18-1.2798.fc6 kernel.

The built in sound card is detected.

--------- o/p of lspci --------------
00:1f.5 Multimedia audio controller: Intel Corporation 82801BA/BAM AC'97 Audio (rev 12)
-------------------------------------

If I do a lsmod, I do see the sound drivers being loaded. But still no sound.

--------- o/p of lsmod --------------
root@localhost etc]# lsmod | grep snd
snd_rtctimer 7501 0
snd_intel8x0 36445 1
snd_ac97_codec 94945 1 snd_intel8x0
snd_ac97_bus 6593 1 snd_ac97_codec
snd_seq_dummy 8133 0
snd_seq_oss 37057 0
snd_seq_midi_event 11841 1 snd_seq_oss
snd_seq 57137 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi_event
snd_seq_device 12621 3 snd_seq_dummy,snd_seq_oss,snd_seq
snd_pcm_oss 46561 0
snd_mixer_oss 20673 1 snd_pcm_oss
snd_pcm 80453 3 snd_intel8x0,snd_ac97_codec,snd_pcm_oss
snd_timer 27077 3 snd_rtctimer,snd_seq,snd_pcm
snd 57029 11 snd_intel8x0,snd_ac97_codec,snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd _timer
soundcore 14113 1 snd
snd_page_alloc 14281 2 snd_intel8x0,snd_pcm
-------------------------------------------

I'm not sure about the modprobe.conf file and was curious if this was right. 'Cause during setup of Fedora after it did the sound test, it asked me if I was able to hear the sound, and I said 'no'. It returned an error saying something like 'sound card not working...has to be configured manually'

I'm attaching my modprobe.conf file

alias eth0 8139too
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0
options snd-intel8x0 index=0
remove snd-intel8x0 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0

If I put a audio CD into drive, it starts playing, but no sound.

Any suggestions please ?

Thanks

Where do i type in the command you suggested?

You open a konsole. In linux there are several and what is installed depends on, your distro, and the choices you made when you installed. It may be called slightly different things, like terminal, or linux console. Look for one. You know you are there if it looks like a dos window.
